What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2019 Mercedes-Benz A 220 4MATIC, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
As of June of 2026 i witnessed my thermostat gauge going from cold to Hot in a back and forth motion. This rising in temperature on the thermostat gauge has happened during acceleration above 45mph, sitting idle with AC on, and while sitting idle after only about 10 mins of car being powered on and in motion. Because the vehicle is under warranty i believed parts would be replaced with new parts but as of today August 11th, 2026, the problem continues and has now been reaching the hot meter on the thermostat gauge. I have sent my car back to my dealer 3 times in a month in a half with the same issue happening repeatedly. Following the second repair period my car stopped unlocking on and off for the days following and now that has been upgraded to a recall issue which was not fixed or truly given any attention at all. This has put me in a hardship position and has not been attended to properly from the first repair. I have In real time recordings of this issue as evidence and am needing some assistance on this matter. I also have the invoices of both repairs which show that no repair was done to the actual affected areas of my vehicle instead they worked on parts that were not of concern.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
